摘要
考虑到微波技术课程教学的需要,提出并开发了Smith阻抗圆图教学软件。归纳分析了软件开发所需要的数学模型;介绍了软件能够实现的主要功能;给出了指导软件开发的系统组成框架,并针对软件的界面设计、负载阻抗的显示以及圆图上轨迹的描绘,阐述了软件设计的指导思想和实现方法。最后,以50Ω匹配到100+j80Ω为例说明了应用所开发软件实施Smith阻抗圆图教学的全部过程。该软件既适合教师上课使用,也适用于学生自学,已经被成功应用于微波技术课程的教学,并取得了良好的教学效果。
Smith Impedance Chart is the basic skill that RF microwave engineers must master,and is the most important content in the teaching of RF microwave course.Considering the needs for the teaching of RF microwave course,a teaching software for Smith Impedance Chart is proposed and developed.First the mathematical model used in developing the software was analyzed,and the main functions of the software were introduced.Then the system framework for the software design was given,and the principle and implementation technique were discussed regarding software interface,impedance display and locus drawing.Finally,an example for 50Ω matching to 100＋j80Ω was illustrated,which described the whole process of Smith Chart teaching by using the software.The software is not only suitable for teaching but also for self-study.It has been successfully used in microwave technology teaching,and a good teaching result has been obtained.
